Martin, a four-year veteran who was born in Jamaica and reared in Canada, started 27 games for the Chargers the last two seasons and amassed 66 tackles and two sacks. His strength is playing the run.

Martin (6-4, 308) was mostly the left defensive end in the Chargers’ 3-4 scheme. In 2011, he took over after Luis Castillo sustained a broken leg in the opener and started the remaining 15 games. He started 12 games last season.

Martin was a fourth-round pick out of Western Ontario (Canada) College in 2009 and was thought to be part of a young Chargers defensive line.

Philadelphia also reportedly has interest in Martin, who could offer depth and versatility similar to that of Tony McDaniel, an unrestricted free agent who seems unlikely to return.
